Description

Technical Field

[0001] This utility model relates to the field of electric vehicle battery swapping technology, and in particular to a positioning and resetting device. Background Technology

[0002] Against the backdrop of the rapid development of the electric vehicle industry, battery swapping technology has become a key means to solve the problem of charging time for electric vehicles due to its advantage of being able to quickly replenish vehicle range. Among them, chassis battery swapping technology has been widely used in the industry because it is compatible with a wide range of models and has a relatively mature battery swapping process.

[0003] The core process of current chassis battery swapping technology is as follows: First, the depleted battery is removed from the battery compartment at the bottom of the electric vehicle, and then transported to a designated location by a transfer trolley. Next, a fully charged battery is transported to the underside of the vehicle by the same transfer trolley and installed into the battery compartment to complete the swap. However, this process is limited by vehicle parking accuracy—due to differences in driver operating habits and parking guidance errors at the battery swapping station, the actual parking position of the vehicle often deviates from the standard parking position. This causes the depleted battery to be offset on the transfer trolley's bearing surface when it is lowered from the battery compartment, meaning the battery position does not match the preset standard bearing position of the transfer trolley. Utility Model Content

[0004] The purpose of this invention is to provide a positioning and resetting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following solution: A positioning and resetting device includes a panel for carrying a battery and two sets of resetting mechanisms correspondingly disposed on the panel. Each of the reset mechanisms includes a reset push block arranged along the first direction of the panel and a drive mechanism that drives the reset push block to reciprocate along the first direction of the panel. A sensor is mounted on the reset push block along its direction of movement, and the sensor is electrically connected to the drive mechanism through the control unit.

[0006] Furthermore, the drive mechanism includes a drive motor, a rectangular pull wire assembly, and a connecting seat; The direction of motion of the output end of the drive motor is perpendicular to the direction of motion of the reset push block; The rectangular pull wire assembly includes four sets of pull wire seats arranged in a rectangle, and each set of pull wire seats is equipped with a rotating wheel that rotates horizontally. The four sets of rotating wheels are fitted with drive cables connected end to end, and the drive cables are rectangular. A portion of the drive cable overlaps with the movement path of the reset push block; The output end of the drive motor is connected to the drive cable; The panel has slots along the movement path of the reset push block; The reset push block is connected to the connecting seat through the slot; The connecting seat is connected to a portion of the drive pull line that overlaps with the movement path of the reset push block.

[0007] Furthermore, it also includes a guide mechanism disposed at the bottom end of the panel; The guiding mechanism includes a slide rail arranged parallel to the movement path of the reset push block and a slider adapted to the slide rail; The connector is connected to the slider.

[0008] As can be seen from the above technical solution, compared with the prior art, the beneficial effects of this utility model are as follows: This invention breaks through the limitations of traditional battery swapping methods on vehicle parking distance. Within the allowable range, as long as the vehicle is parked normally, the reset mechanism can identify or reset the battery position after the battery is received on the panel, thus achieving precise battery swapping.

[0012] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0013] Example 1 See Figure 1-4 As shown, this embodiment provides a positioning and resetting device, including a panel 1 for carrying a battery and two sets of resetting mechanisms 2 correspondingly arranged on the panel 1. Each set of reset mechanisms 2 includes a reset push block 2-1 arranged along the first direction of panel 1 (in this embodiment, it can be defined as the width direction or the length direction, depending on the actual situation) and a drive mechanism 2-2 that drives the reset push block 2-1 to reciprocate along the first direction of panel 1. A sensor 2-3 is mounted on the reset push block 2-1 along its direction of movement. The sensor 2-3 is electrically connected to the drive mechanism 2-2 through the control unit.

[0014] It should be noted that the two reset push blocks 2-1 move closer or further apart under the drive of the two drive mechanisms 2-2.

[0015] It should be noted that the detection direction of sensor 2-3 is parallel to the movement direction of reset push block 2-1, and the detection directions of sensor 2-3 on the two reset push blocks 2-1 are opposite to each other.

[0016] Specifically, the reset mechanism 2 records the position information of the side wall of the battery (or battery compartment) and pushes to adjust the side wall, thereby ensuring that the battery (or battery compartment) can be position recorded and adjusted, ensuring accuracy.

[0017] Specifically, such as Figure 3 The drive mechanism 2-2 includes a drive motor 2-201, a rectangular pull wire assembly 2-202, and a connecting seat 2-203; The direction of motion of the output end of the drive motor 2-201 is perpendicular to the direction of motion of the second reset push block 2-1; The rectangular guy wire assembly 2-202 includes four sets of guy wire seats 2-2021 arranged in a rectangle, and each set of guy wire seats 2-2021 is equipped with a rotating wheel 2-2022 that rotates horizontally. Four sets of rotating wheels 2-2022 are fitted with drive cables 2-204 connected end to end, and the drive cables 2-204 are rectangular; A portion of the drive cable 2-204 overlaps with the movement path of the reset push block 2-1; The output end of the drive motor 2-201 is connected to the drive cable 2-204; A slot 1-1 is provided on panel 1 along the movement path of reset push block 2-1; The reset pusher 2-1 is connected to the connecting seat 2-203 through the slot 1-1; The connecting seat 2-203 is connected to a portion of the drive pull wire 2-204 that overlaps with the motion path of the reset push block 2-1.

[0018] When the output end of the drive motor 2-201 extends or retracts, it drives the drive cable 2-204 to rotate, which in turn drives the connecting seat 2-203 to move, and further drives the reset push block 2-1 to move.

[0019] In addition, to ensure the movement direction of the reset push block 2-1, a guide mechanism 2-4 is also included at the bottom of the panel 1, see Figure 4 The guide mechanism 2-4 includes a slide rail arranged parallel to the movement path of the reset push block 2-1 and a slider adapted to the slide rail; the connecting seat 2-203 connects the slider.

[0020] Specifically, panel 1 can be installed on top of the transfer trolley to facilitate battery adjustment and transfer in conjunction with the transfer trolley.

[0021] It should be noted that sensor 2-3 is a proximity sensor. After sensor 2-3 detects proximity, it sends a stop operation command to drive motor 2-201. The PLC records the distance pushed out by the push rod of drive motor 2-201.

[0022] Specifically, this technology can adjust the position of the battery carried on the panel 1 by cooperating with two sets of reset mechanisms 2. After the battery is removed, it can be adjusted to a suitable position. When the battery is installed, it can also be readjusted back to the position suitable for vehicle installation. That is, adjustments can be made after the battery is removed and adjustments can also be made when the battery is installed.

[0023] This document uses specific examples to illustrate the principles and implementation methods of this utility model. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of this utility model. Furthermore, those skilled in the art will recognize that, based on the ideas of this utility model, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of this utility model.
